I have made a web based and mobile app that has a basic profile function. I was working well few weeks ago now it's pretty weird both apps can't log me in even with correct inputs. I didn't change anything in the codes so I doubt it's the problem and I have checked it millions of times.

The URL are correct everythings fine with the code what and the database is still there. I'm thinking it's a problem with the database itself.I am using XAMPP is a scenario like this possible?

I have tried turning off the xampp server but it only causes an endless loop on verifying the account
